Specification of Letters Patent.

Patented July 22, 1913.

Application filed June 25, 1906. Serial No. 323,259.

To all whom, it may concern Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and State (if Connecticut, have invented a new and useful Improvement in Cutting and Folding Machines, of which the following is a specification.

In the production of a magazine or periodical from a press it has frequently been impossible to obtain the proper combination of sheets from the press alone to provide for the number of pages required in the said magazine or periodical.

The object of this. invention is to pro vide separate sources of web sheet supply placed adjacent to the cutting, collecting and folding machine and provide automatic sheet cutting and feeding mechanism for said separate sources of extra web sheet supply whereby extra sheets may be fed at the proper time into position to be assembled with the sheets from the press, the assembling of the extra sheet or sheets with the sheets from the press being accomplished before the sheets are stitched and given their final fold.

It is intended that the sheet feeding mechanism for the separate web sheet supply shall be so timed with respect to the mechanism for feeding the sheets from the press that the sheets from the separate sources of web sheet supply may be used either as in sert sheets or as cover sheets as may be desired. In. the present case two separate sources of extra web sheet supply are shown for the purpose of illustrating the operation of the invention.

In the accompanying drawings, Figure l is a view in side elevation of a portion of the cutting, collecting and folding machine indicating the geared connections between the several parts; Fig. 1 is a detail section taken inside the frame, showing the collecting and transfer-eylinders, their adjacent parts and the cams for operating the grippers on the 'transfer cylinderyFig. 2 is a vertical section through the portion of the machine shown in Fig. 1, taken in the plane of the.line A Aof Fig.3; Fig. 2" is a detail section showing in top plan the mechanism for controlling the operation of the collecting cylinder; Fig. 2 is a detail sectional view taken in the plane of the line B-B of Fig. 2 with the collecting and .transfer'c lindersshown in broken lines and the trans er cylinder gear shown in dotted lines; Fig. 2 is a detail side view of part of the mechanism for controlling theoperation of the collecting cylinder; Fig. 3 is a front view of the portion of the machine shown in Fig. 1; Fig. 4 is a vertical section taken in the plane of the line C-C of Fig. 1; Fig. 5 is an extension of the View shown in Fig. 1, from the line 5 -5; Fig. 6 is an extension of the view shown in Fig. 3 from the line 66; Fig. (3 is an extension of the View shown in Fig; 6; Fig. 7 is a vertical section through the part shown in Fig. 6, taken in the plane of the line C*C* of Fig. 5, which forms an extension of the line C- C of Fig. 1; Fig. 7 is an extension of the view shown in Fig. 7; Fig. 7 is a detail view of the anvil cam which controls the operation of the stapling mechanism; F ig.

The cutting, collecting and folding machine which is illustrated 'in the accompanying drawings is one which is adapted Q for use in connection with a perfecting printing press of the rotary type. The side frames of the machine are denoted by 1 and 2, in the top .of whicli side frames there are u ountedjn suitable bearings web the rotary cutters 8, 9, mesh\\vith each other and the gear 10 meshes with a gear 12 which in turn meshes with a gear 13 on the feeding roller 4. Gears 1.4, 15 connect the rollers 3, 4 and gears 16, 17, connect the rollers 5, 6. An intermediate idler gear 18 connects the gear 15 with the gear 16.

Sheet guides 19, 20 are mounted in the side frames 1 and 2 in position to direct the sheets from the rotary cutters 8, 9 into position to be engaged by a set of grippers 21 carried by a transfer cylinder 22 also mounted in the side frames 1 and 2. A delivery cylinder 23 is mounted in the side frames 1 and 2 and is pro ided with a set of grippers 24 arranged to successively receive the advance edges f a group of two sheets and deposit the same on to tapes 25 which are arranged to carry the group of two sheets to the sheet receiving table 26. These tapes 25 pass around rollers 27, 28, 29, suitably mounted in the side frames 1 and 2. A plurality of slitters 30 are mounted in the side frames 1 and 2 in position to slit the groups of sheets while on the delivery cylinder. In the present instance I have shown three of these slitters so that each group of two sheets is divided into four groups as they are fed on to the table 26.

Mechanism is provided for controlling the movement of the grippers 21 on the trans fer cylinder 22 so that the said grippers may have a short opening to receive the first sheet from the cutters and a long opening for receiving the advance edge of the next succeeding sheet from the cutters and. transfer the two sheets to the grippers 24 of the delivery cylinder 23, This mechanism is constructed as follows A cam provided with a long surface 31 and a short surface 32 has a laterally sliding movement on studs 33, 34, projecting from the side frame 2, which cam is moved by a two-armed rock lever mounted on a lug 35 of the frame 2, one arm 36 of which rock lever is engaged with the latera y movable cam 31, 32, and the'other arm 37 of which lever is provided with a stud 38' which is fitted to travel in an. irregular groove 2%) of a rotary cam 40 fixed to the shaft of the delivery cylinder 23. The long surface 31 or the short surface 32 of the laterally movable cam may be brought into position to engage the truck roller 41 of the set of grippers 21 at the proper times so that during one revolution of the transfer cylinder 22, the truck roller 411s caused to travel over the short surface from the 32 and during the next revolution the said roller is caused to travel over the long surface 31 of the said cam.

The truck roller 42 of the set of grippers 24 on the delivery cylinder 23 is caused to travel over the stationary cam 43 on the side frame 1 for causing. the grippers to open to receive the advance edges of two sheets grippers 21 of the transfer cylinder 22.v A second stationary cam 44 is carried by the side frame 1 in position to engage the ,truckgroller'42 and cause the grippers 24 to-open to deliver the collected group of two sheets onto the tapes 25 to be fed on to the sheet receiving table 26.

The four groups of two sheets may be brought into proper registeron the sheet receiving table, 26 before they are assembled, by the folding mechanism. A sheet stop 45 is located along theouter end, of the sheet receiving table 26 in position to receive the outer edges of the four groups of two sheets. arranged to be brought above the plane of the table in position to strike the inneredges of the four groups of sheets. These Joggers are denoted by 46 and they are afiixed 'to a. cross shaft 47 which is mounted *to rwk in the outer ends of rock arms 48 aflixed -,to a roekshaft 49 mounted in the side frames 1 and 2. These joggers 46 are movedabove and below the plane of the table 26 by providing the rock shaft 49 with an arm 50 having a depending rod 51 provided at its lower end with a yoke 52 which embraces the central cross shaft 53 of the machine so as to guide the arm 51 in its vertical'movements. A cam 54 is fixed to the rotary shaft 53, which cam is provided with a face 55 is such that the shaft 49 will be rocked A plurality .of joggers are Y to raise and lower the joggers 46 at the proper times.

An independent rocking movement is imparted to the joggers 46 by providing the arm 57 fixed to the cross shaft 47, with a cam surface 58 arranged to engage with a laterally sliding spring-actuated tripping arm 59 mounted in the side frame 1. The inner end of the cam surface 58 on the arm 57 is located adjacent to the vertical wall 60 of a recess 61. A spring 62 is arran ed between a lug 63 on the sideframe 1 an a shoulder 64 carried by a sliding pin 65 hinged to the arm 57, which spring tends to return the arm and thereby the joggers 46 to the limit of their forward movement.

The laterally sliding tripping arm 59 is provided with a spring 66 tending to hold the arm in the path of the jogger arm 57. The top of this tripping arm 59 is provided with a cam surface 67 whichis arranged to coact with the wall 60 of the recess 61 in the arm 57, which wall is arranged at an will force the arm 59 inwardly out of its.

path. From the above description it will be seen that as the arm 57 is raised, the joggers 46 will be swung rearwardly until they are permitted to snap back by the passing of the cam surface 58 beyond the arm 59.

A train of spur gears 68, 69, 70, conmeets the spur ear 71 on the delivery cylinder 23 with t e main drive Spur gear 72 fixed to the cross shaft 73 mounted in the side frames 1 and 2, which spur gear 72 may be driven from any suitable means from the press, not, shown herein. his spur gear 71 meshes with a spur gear 72* which in turn meshes with a spur gear 73* fixed to the shaft of the rotary cutter 9 the spur gear 73 on said shaft of the rotary cutter 9. in turn meshing with a spur gear 7 4 aflixed to the shaft of the rotary cutter 8. The spur gear 71 also meshes with a spur gear 75 aflixed to the transfer cylinder 22.

The means shown for assembling the four "groups of two sheets each together is congroups of two sheets each at one side of the machine and the opening 79 being located beneath the side edges of the other two groups of two sheets each at the other sideof the machine. Directly above these adjacent side edges are located vertically sliding V-shapcd guides 80, 81, which are pro-- vided with studs 82, 83, arranged to travel in cam grooves 84, 85, in the faces of cams 86, 87, atiixed to a rotary cross shaft 88 mounted in suitable bearings in the side frames 1 and 2. Adjacent to the V-shaped guide 80, on opposite sides of the same, are provided positively rotated feeding pulleys 89, 90 carried by the lower arms 91, 92, of rock levers pivoted at 93, 94, the upper arms 95, 96, of said levers having studs 97, 98, fitted to travel in peripheral cam grooves 99, 100 of cams 101, 102 affixed to rotate with the crossr'shaft 88. Similarly, positively driven feeding pulleys 103, 104, are mounted in the lower arms 105, 106 of rock levers pivoted at 107, 108, the upper arms 109, 110 of which are provided with studs 111, 112 arranged to travel in peripheral cam grooves 113, 114 in cams 115, 116 fixed tdf rotateivith the cross shaft88. Feeding rollers 117, 118 are located directly beneath the guide below the table 26 and feeding rollers 119, 120 are located directly beneath the guide 81 below the table 26. The feeding rollers 117, 118, are arranged to receive between them the adjacent side edges of two groups of two sheets each at one side of the machine and feed them between sheet earrving tapes 121, 122, which tapes in turnfeerLth-e sheets on to a stitcher table 12 3.

The feeding rollers 119, 120 are similarly arranged to receive between them the adjacent side edges of the other two groups of two sheets each and feed the said sheets between sheet carrying tapes 124, 125, which tapes in turn feed the sheets on to the stitcher table 123 where the four groups of two sheets each are assembled together.

. The sheet carrying tapes 121 pass around pulleys 126 beneath the feeding rollers 117, 118, pulleys 127 adjacent to the upper end of the stitcher table 123 and idler pulleys 128. The sheet carrying tapes 122 pass around pulleys 129 beneath the feeding rollers 117, 118, a roll 130 adjacent to the upper end of the stilcher table 123 and intermediate idler pulleys 131. The sheet carrying tapes 124. pass around pulleys 132 beneath the feeding rollers 119, 120, pulleys 133 adjacentto the upper end of the stitcher table 123 and intermediate idler pulleys 134. The sheet carrying tapes 125 pass around pulleys 135 beneath the feeding rollers 119, 120, pulleys 136 spaced a short distance above the upper end of the stitcher table 123 and around intermediate idler pulleys 137. Guides 138, 139 are arranged b tween the feeding rollers 117, 1.18 and the tape pulleys 126, 129. Guides 140, 141 are arranged between the feeding rollers 119, 120 and the tapepulleys 132, 1235. Guides 142, 14-3 are arranged in position to direct the two groups of two sheets each from their carrying tapes on to the stitcher table 122-3.

The cross shaft 88 is driven from the delivery cylinder gear 71 through spur gears 1.44, 145. A' cross shaft 146 is suitably mounted in the side frames, which cross Shaft is driven from the spur gear 14.5 through spur gears 147, 148, 151-9. The cross shaft 1416 is provided with a bevel gear connection 150, 151 with the shaft of the feeding roller 117 and a similar bevel gear driving connection 152, 153, with the feeding roller 120. The roller 117 has a spur gear driving connection 154-, 155 with its other roller 118; and the roller 120 has a spur gear connection 156, 157 with its other roller 119. Rotary movement is impar1cd to the feeding pulley 89 from the roller 117 through a train of spur gears 158, 1.19, 1601 Rotary movement is imparled to the feeding pulley from the feeding roller 118 through a train of spur gears 161, 162, 163. Similarly the feeding pulleys 1021, 10-1 are driven from the feeding roller-z 119. 120 through trains of spur gears 16-1. 16.), 166 and 167, 168, 169 respectively. The sheet carrying tape pulleys 126, 120 are driven from the feeding roller gear 151- through a sheets at a predetermined time.

nected to one arm 190 of a roclr lower end of the stitcher table 123, which sheet stop is arranged in' position to be brought into engagement with the table for receiving the advance edges of the assembled sheets and to be moved away from the table for releasing the collected group of The niecha nism for operating this sheet stop comprises a cam 177 on a cam shaft 178, which cam 177 engages a stud 179 on a longitudinally movable connecting rod 180, the upper end of which is connected to one arm 181 of a rock lever pivoted at 182, another arm 183 of which-lever carries the sheet stop 176. A third arm 184 of said rock lever is under the influence of a spring 185 tending to hold the sheet sto in engagement with the carrier table and the connecting rod 180-at the limit of its downward movement with its stud 179 in engagement with the periphery of the cam 177. a

Any well known or. approved stitching mechanism might be employed for stitching the assembled sheets together. In the pres ent instance the stitcher anvil is denoted by 186, the movement of which anvil is con trolled by a earn 187 on the cam shaft 178, through a longitudinally movable connecting rod 188 having a stud roller 189 bearing against the periphery of the cam 187, the upper end of which connecting rod is con-- lever pivoted at 191, another arm 192 of which is connected by a link 193 to the anvil 186. A third arm 194 of this rock lever is under the influenceof aspring 195 tending to force the stitcher anvil toward the stitcher table and the connecting rod.188 at the limit of its downward movement with its stud roller 189 in engagement with the periphery of its cam 187.
